Whenever I learn a theory or a concept in science, I keep asking too much of why? and how? questions. An example would be this:https://www.physicsforums.com/showthread.php?t=765366 and this:www.physicsforums.com/showthread.php?t=746990 But when I don't ask such type of silly questions, I feel as if I haven't understood the material and lack something in it. Also I keep asking myself this type of questions even for certain principles like piezo-electric property(why is it that when we apply force on 1 side, we get electric charges on the other. How is that possible in the real world?). Also I learnt that Frequency band for Standard AM broadcast ranges from 540 to 1600 kHz(But my question is why? how exactly do they determine this range?) Are asking such kind of questions awkward? If yes, then what exactly is the way to understand fully the concepts behind each topic in science?
